Specification of Letters Patent.

Patented Nov.. 5, i913..

Application filed February 1, 1916. Serial No. 75,535.

To all lwhom it may concern:

Be it known that l, FRANK H. VAN HOUTEN, a citizen of the United States, residing at Beacon, in the county of Dutchess and State of New York, have invented certain new and useful Improvements in Dougli-Dividing Machines; and l do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanyingv drawings, forming part of this specification.

rll`his invention relates to dough dividing machines of that type wherein the dough is fed from a compression chamber into measuring pockets in a movable head or cylinder, each of said pockets having within it a plunger which is retracted for the admission of a new charge of dough and advanced to discharge the dough from the pocket when the head has moved to bring the pockets out of registry with the compression chamber.

Machines of this type have embodied a number of different mechanical arrangements of parts and for the purpose of illus trating thepresent invention, l have adopted a machine of the general type shown in my prior Patent No. 1,158,339. 1n dough dividing machines of this type it quite frequently happens that a film or layer of dough clings to the surface of the measuring cylinder after the pockets have left the compression chamber and also the dough is apt to cling to the surface of the cylinder during the discharge of the dough when the plungers are advanced. lt is most desirable that the surface of the. cylinder be kept free of dough at all times, in order that the cylinder and other parts may work smoothly and also to mainu tain clean conditions in the machine.

The object of the present improvement is to provide a very simple and efficient arrangement which will keep the surface of the cylinder free from dough at all times and also apply a lubricant to the surface of the cylinder after the discharge of the dough from the pocketsand during return of the pockets to filling position. Although fthe invention, for convenience, is shown as applied to dough dividing machines of the type disclosed in my prior Patent No. 1,158,339, it will be understood that the in vention. is not to be limited to this specific application but may be embodied in other types of dough machinery as well.

rlhe invention consists in the construction, arrangement and combination of parts hereinafter set forth, and the novel features of the invention will be particularly pointed out and specified in the claims at the end of the specification.

ln the drawings:

Figure 1 is a side elevation partly insection of a dough dividing machine embodying the present improvements.

Fig. 2 is a bottom plan view of a portion of the dough hopper, illustrating in detail the improved gib which forms one of the members keeping the surface of the cylinder free from dough.

Fig. 3 is a detail side elevation of the improved combined oiler and scraper.

Fig. 4e is an end view of the same looking in the direction of the arrow.

Fig. 5 is `an end view looking in theopposite direction from that of Fig. a.

Like characters of reference in the sev eral figures indicate the same parts.

The machine adopted for illustrating the present invention embodies in its construction a hopper A into which the dough to be divided is deposited, and the discharge end of said hopper leads into a` compression chamber B. Working within the compression chamber is a reciprocatory plunger or head C adapted to advance the dough into the measuring cylinder D and t0 force the same into the pockets in said cylinder at a substantially predetermined pressure. The

operating mechanism for the plunger is in its general characteristics `similar to that disclosed in my prior Patent No. 1,158,339, and

may be briefly described as follows:

A. cam shaft F is journaledin the frame li" of the machine and receives rotary motion through the medium of a large gear wheel G `meshing at one end with` a pinion Gr which forms part of a train of drive gearing deriving power` from any suitable source, not shown. A weighted bell crank lever formed by the arms g, g', is mounted on a transverse shaft g2, the arm g being pivotally connected by. a link connection g3 with the rear end of the plunger C, while an adjustable weight gL is mounted on the` arm g. rlfhe weight gt serves as the means for end with. a drum or are' 'in' filling advancing the plunger and dough and for forcing the dough into the lineasuring pockets, while av cam g5 on the shaft F serves as the means for retracting the plunger and elevating the weight g4. The measuring cylinder or drum E having the chambers or pockets therein for the reception of the dough, is j ournaled in bearings c in the main frame and at one end is provided with means whereby it is given an intermittent lrotary movement, in the present instance each movement corresponding to substantially one-half of a revolution. The mechanism for'rotating the cylinder is similar to that n owin use and, briefly, it embodies a chain oriiexiblelconnection E connected atone end with a crank pin e" eccentric'ally mount'- ed on the gear wheel G and'at the opposite i pulley E2 journaled on the'end ofthe cylinder E and adapted to connect therewith through a pa'wl and ratchet connection, not herein illustrated. It will bejun'derstood that one-half a revolution' of the cylinder E through the medium of the above vdescribed connections willjoperate to bring one series of measuring pockets Dk into registry with the discharge end of the compression chamber B and simultaneously to'carry another series of measuring pockets D out ofregistry with the compres sion' chamber. Within the pockets are plungers Zz which'are retracted when vthe pockets position, the pocketsD being shown in filling4 position in Fig. A'l' of the drawing. The said plungers are advanced as thel pockets are carried vaway from filling position 'during onejhalf a revolution ofthe cylinder E, in thedirection of the arrow,

' an`d the advancey movement of the plungers will operate," as'will beunderstood, to discharge/the dough fromthe pockets` on toa takeoff' roller "The present invention is`A` particularly concerne'd with the provision Of 'a I lvQVel arrangement forkeeping' the surface' of' the l'measuring cylinder E at alltitmesfreefrQm ough "thisbeihs a. moet .desirable eondtien 11,011 only for, thesakeof Cleanlinessbut also to permit @ase in 'Qpe'ration of themaehn.

The is lillustrated in detail in F ig. 2 vof. the drawings'a'nd is secured to the wall I by means of adjustment. Screws k ,fitted-'in Suitable sockets connecting the inner wall of the recess z' with the interior of the hopper A. ese screws provide a means for adjusting the position of the scraping edge of the gib K relatively to the surface of the cylinder E. It will be noted that the gib engages that portion of the surface of the cylinder E following the pockets which have just been filled by the advancing movement of the plunger and thus any particles of dough remaining in the compression chamber which would otherwise be carried around by the surface of the cylinder E are scraped off by the gib,

At the discharge end of the machine is mounted a pair of spaced bracket arms L, L. These bracket arms are respectively journaled on'the pivots Z, Z in the frame F and ysupport between them at their lower ends the combined oiler and scraper. The combined oiler and scraper consists of a relatively long bar pivotally mounted by means of the shaft m between said bracket armsL, L andv having at its end facing the discharge edge M which is held in surface of the cylinder E by the bracket arms. The other end of the bar M is formed with a trough O running substantially the entire length of the bar and ttcd with] a strip of suitable absorbent material, such as a wick, O brushing against the surface of the cylinder'E. Eachv bracket arm is provided at its upper end with a bearing p receiving an adjusting screw P, the inner ends of which are 'adapted to engagel a fixed portion of the frame, such as the parts e. By rotating thev handlesv of the adjusting screws of the two bracket arms the position of, the bar M may be adjusted relatively to the surface of the cylinder E. A supply of lubricant is supplied to the trough below by means of an oil tube g suitably supported inthe frame F and having at its upper end an oil cup Q, of any well known type. The oil feedq may be regulated by means of a needle valve Q.

vIt will be noted that after the dough is discharged on to the take-0H roller H the surface ofthe cylinder E is rotated into contact, with the scraping edge Mv of the. bar M and hence anyy particles of dough are scraped olf the surfaceof the cylinder. The rotating surface isnext brought' into contact withithe wick O which swabs a thinihn of oil or other suitable lubricant over the face vof the cylinder@ In the'p'resent arrangement the two Scrapers, namely, the gib K and 4thebar M are positioned atv the pointswhere there lis the greatestjliability of dough beingy deposited on the vface or surfaceofthe cylinder, this being just after Contact with the the fillingI of the pockets and just after the discharge of the dough from the pockets. is a,y result the surface of the cylinder is end of the machine a scraping kept clean of dough, thereby insuring practically sanitary conditions in the machine and free running of the mechanism at all times.

What is claimed is l. A combined oiler and scraper for dough measuring cylinders and the like, embodying a support, a member pivoted to said support having a scraping edge at one end and a trough at the other end, said trough and scraping edge both substantially coextensive with the length of the measuring cylinder, a stripu of absorbent material in said trough adapted to brush against the surface of the cylinder, and a tube for supplying a lubricant to said trough.
